robot_state_publisher electric issue
Hi,
I moved from Diamondback to Electric and I have some issues with the robot_state_publisher. Simply put the problem is: /tf published does not contain all the frames. Note that this was working well on diamondback.
To elaborate: /joint_state are published @100Hz from an Orocos component and one of them looks like the following.
header:
seq: 30197
stamp:
secs: 0
nsecs: 0
frame_id: arm_0_link
name: ['arm_1_joint', 'arm_2_joint', 'arm_3_joint', 'arm_4_joint', 'arm_5_joint', 'arm_6_joint', 'arm_7_joint']
position: [0.85575544023703909, -0.60253893146418169, 0.69191502336820099, -0.69900108242376158, -0.69835294705758466, -0.10636135673431404, -0.29402346125214407]
velocity: []

The /tf published by the joint_state_publisher(in electric) is the following:
header:
seq: 0
stamp:
secs: 1320055266
nsecs: 436124783
frame_id: /base_link
child_frame_id: /arm_0_link
transform:
translation:
x: 0.0
y: 0.0
z: 0.01
rotation:
x: 0.0
y: 0.0
z: 0.0
w: 1.0
All the other Frames are missing.
This is my launch file:
<launch>
<!-- Load arm into parameter server -->
<param name="robot_description" command="$(find xacro)/xacro.py '$(find re_kuka)/description/robots/lbr.urdf.xacro'" />
<!-- State publisher -->
<node name="robot_state_publisher" pkg="robot_state_publisher" type="state_publisher" >
</node>
<node pkg="rviz" type="rviz" output="screen" name="rviz" />
</launch>
FYI:
I don't see any parsing errors when I launch. I checked the urdf file using:
demoelec@totoro:~$rosrun xacro xacro.py /home/demoelec/ros/stacks/trajectory-generator/re_kuka/description/robots/lbr.urdf.xacro > lbr.urdf demoelec@totoro:~$ rosrun urdf check_urdf lbr.urdf robot name is: lbr ---------- Successfully Parsed XML --------------- root Link: base_link has 1 child(ren) child(1): arm_0_link child(1): arm_1_link child(1): arm_2_link child(1): arm_3_link child(1): arm_4_link child(1): arm_5_link child(1): arm_6_link child(1): arm_7_link
robot_state_publisher is running and corresponding topics were published
demoelec@totoro:~$ rosnode ping /robot_state_publisher rosnode: node is [/robot_state_publisher] pinging /robot_state_publisher with a timeout of 3.0s xmlrpc reply from http://totoro:38288/ time=0.640869ms
demoelec@totoro:~$ rostopic hz joint_states subscribed to [/joint_states] average rate: 100.008 min: 0.009s max: 0.010s std dev: 0.00013s window: 98

To reproduce:
git clone git@github.com:IDSCETHZurich/trajectory-generator.git
roscd re_kuka/launch (no need to rosmake)
rosbag play ./joint_states.bag -l
roslaunch ./visualize.launch
I would appreciate any help/hints solving this.
Best Regards, Gajan
